WALL BOARD.

Application filed November The present invention relates to new anduseful improvements in wall board and it pertains more particularly to acomposition board for use In facing Walls in buildings.

It is one of the primary objects of the invention to provide a wallboard which may be used in the erection of walls, which board will giveto the completed wall a finished appearance.

It is a further object of the invention to construct the wall board insuch a manner that when a plurality of the boards are used together, thejoint or seam between the several boards may be. effectively concealed.

It is a further object of the invention to construct the wall board froma plurality of different materials with a reinforcing element interposedbetween the two materials employed.

It is a further object of the invention to provide a reinforcing elementfor wall board which reinforcing element is capable of takingfastenings, such as nails, screws, or the like.

With the above and other objects in view, reference is bad to theaccompanying drawings, in which- Figure 1 is a plan view partly brokenof a section of wall board formed in accordance with the presentinvention;

Fig. 2 is a detail transverse sectional view taken on the line 22 ofFig. 1;

Fig. 3 is an enlarged plan view partly broken away to show theconstruction of the wall board, and i I Fig. 4 is a plan sectional viewof a por lion of a wall constructed from well board formed in accordancewith the present invention.

Referring again to the drawings and more particularly to Fig. 2, it willbe noted that the wall board comprises a body portion 5, a facing 6, areinforcing element 7 and reinforcing elements 8. The body pormaterialas is also the facing 6, and these materials are combined together toform a section of wall board. In uniting the body portion 5 and thefacing 6, however, the reinforcing element 7 is interposed therebetweenas shown in Fig. 2. This reinforcing 17, 1925. Serial No. 69,691.

element 7 consists of a sheet of suitable fabric and is preferably of arelatively open weave to permit of the materials of the body and thefacing passing therethrough in order to interlock on opposite sidesthereof.

The reinforcing elements designated by the reference numeral 8 arewooden strips which are embedded in the body portion, and as shown inFig. 2, the fabric reinforcing element 7 is wrapped around the edgedefining reinforcing strip 8 as designated by the reference numeral 10.A similar reinforcing strip of wood, 9, extends longitudinally of thesection of wall board when completed, and such reinforcing strip 9 iswrapped or bound with a fabric reinforcing element designated by thereference numeral 11.

Each of the sections of wall board is formed with beveled side edges asdesignated by the reference numeral 12, and the min forcing strips 8extending along the side of the wall board are adapted to underlie aportion of the beveled edge 12 in order that nails inserted through thebevel will pass through the reinforcing strip and secure the wall boardin position.

In Fig. 4 is shown the manner of erecting a wall with wall boardconstructed in accordance with the present invention, and in such figurethe reference numeral 15 designates the studding and 16 designates asection of wall board. Fastenings 17, such as nails or the like, aredriven through the beveled edge 12 of the sections of wall board andthrough the reinforcing elements 8 as shown. By providing the bevelededges as shown, a channel 18 is provided and such channel is filled witha suitable finishing 9 plaster or the like, 19, to give a finish to thecompleted wall, and also to aid in maintaining the fastenings 17 inproper position,

From the foregoing it is apparent that the present invention provides anew and improved wall board. Thus all of the ob jects of this inventionhave been accomplished, and, further, it will be understood thatnumerous modifications of structure may readily be resorted to withoutin the least departing from the scope of the claim.

What is claimed is;

A wall board comprising a. oeinentitious body, wooden strlps whollyenclosed in an H open weave fabric and embedded in the body, acementitious facing for the body,

said facing having a portion of its ends thlckened, and a sheet of anopen weave :t'abrio between the body and racing and PAUL THEODOREBEYGRAU.
